Quality of service definition

Quality of service or “QoS” usually refers to a tool that manages network resources to guarantee better performance for some critical tasks over the less important ones. For example, VoIP and video conferencing receive better treatment for an uninterrupted low-latency performance. Furthermore, QoS facilitates security monitoring by quickly sending security alerts and logs, which can help promptly react to cybersecurity threats.

Typical quality of service (QoS) examples in cybersecurity:

  • VoIP prioritization: QoS can favor traffic for VoIP communications to ensure clear and uninterrupted voice calls, especially in periods of high network usage. Furthermore, this provides more security in communication channels.
  • Security monitoring traffic: QoS favors security-related systems, like intrusion detection systems (IDS) and event management system (SIEM) platforms. They ensure precise, timely delivery of various security alerts, which are crucial for fast threat response in cybersecurity.
  • Video conferencing: During a video conference, QoS can be applied to give priority to video and audio data, preventing lag or dropped calls. This is vital for secure remote meetings and discussions involving sensitive information.
